Stationary acoustic detectors (Wildlife Acoustics Song Meter SM4) were deployed to capture 
echolocation data over time. Bat calls parameters known for European bat populations 
(Barataud, 2015) and bat species from neighbouring countries for Uzbekistan (Benda et al., 
2012) were used for identification and analysis. 
Further, the possible location of bat roosts, which would be used by residential bats, maternity 
colonies, hibernating bats, and for mating, is of importance to understand. Specialized bat 
roost searches were undertaken within the project boundaries and area of influence.

The detectors were deployed in Autumn 2020 as well as Spring and Summer 2021. This covers 
the 7-
month ‘active’ period for bats in Uzbekistan. 
Bat roost search surveys were undertaken in Spring 2021 and Summer 2021. 
7.1.3.2
Results 
The acoustic monitoring surveys ultimately found a number of bat species utilizing the site, but 
a generally low density of bats. No species of elevated status or concern were recorded.
